ABSTRACT:
The invention relates to a process for preparing polymers by bulk polymerizing a monomer feedstock composed of styrene or styrene-like monomers and/or anionically copolymerizable comonomers employing an anionic initiator and a conventional spray-tower as reactor in the absence of a quenching solvent that fills the lower portion of the spray-tower, and the polymers so produced.
